If \(3x - 10 = 17\), what is the value of \(6x + 20\)?

Asked by DianePorcelli991

Answer (3)

3 x − 10 = 17 / + 10 3 x − 10 + 10 = 17 + 10 3 x = 27 / : 3 3 x : 3 = 27 : 3 x = 9 6 x + 20 = 6 ⋅ 9 + 20 = 54 + 20 = 74
3 x − 10 = 17 / ⋅ 2 2 ⋅ 3 x − 2 ⋅ 10 = 2 ⋅ 17 6 x − 20 = 34 / + 40 6 x − 20 + 40 = 34 + 40 6 x + 20 = 74

74 because 3x equal 17+10. so x equals 9 and plug it in to the equation got 74

To solve the equation 3 x − 10 = 17 , we isolate x to find x = 9 . Substituting this value into 6 x + 20 gives us 74 . Therefore, the final answer is 74 .
